The teams of Who veterans who’ll be putting their knowledge to the test on the left-field quiz show are: Bernard Cribbins (Wilfred Mott) and Jacqueline King (Sylvia Noble), Nicola Bryant (Peri) and Andrew Hayden Smith (Jake Simmonds), Sylvester McCoy (the Seventh Doctor) and Sophie Aldred (Ace), and Louise Jameson (Leela) and Frazer Hines (Jamie).
Hosts Alexander Armstrong and Richard Osman will also have some help on the show from the Doctor’s robotic helper K-9.
The aim of the game in Pointless is to score the fewest points possible by answering questions with obscure bits of knowledge. Each question on the show is asked to a panel of 100 people to determine both the most obvious and bizarre answers, and the show’s Holy Grail is an answer that none of the survey’s sample thought of.
Only one pair of the special’s time travelling teams can win the show’s trophy and advance to the final round, where all that stands between them and a big cash prize is one last Pointless brainteaser.
The Pointless Doctor Who special will air on Saturday 23 March at 6:00pm on BBC1.
